The project team can be understood. The application needs the first customers who wish to download their documents for verification. That's why the team decided to organize a free distribution of tokens.
This is a common practice. I had to deal with such a project, where I had to make my resume so that it was presented to the employer. There are also many projects in which you need to create an account.
If a person plans to go to another country and make a resume, then, of course, he will need all this. But if there is nothing like that in the plans, then you can not waste your time on uploading the diploma to the app.
Now many people work in internet. Thanks internet it is possible to get job anywhere in the world. And such application where it is possible to download diplomas will be very useful.
